Definitions:
•“Operations Management
is the set of activities
that creates value that creates value
in the form of goods or services
by transforming inputs into outputs.”-Jay Heizer and Barry Render.

Cars that stop or slow down automatically before an object or person in anticipation of a possible crash are not new. But Toyota’s latest
pre-collision system adds a steering-control feature. In the new system, Toyota uses cameras
and a super sensitive radar called “millimeter-wave”, both installed in the front of the vehicle , to detect possible crashes such as a pedestrian crossing the road. The vehicle calculates how
braking and steering must be applied to avoid a crash, said chief safety technology officer……

Production System
The elements are:
•Inputs-The basic needs or resources of the system (Land, Building, equipment, capital, raw material etc.)
•Transformation process-Value addition •Transformation process-Value addition process(manufacturing processing, information processing or customer processing)

Production Function/SystemThe elements are:
• Outputs-Desired result of the system, may be goods or services.(output should be of Stakeholders' interest)
• Random disturbances-Both controllable and • Random disturbances-Both controllable and uncontrollable factors influence, causing the difference between planned and actual output.
• Feedback Mechanism-Comparing Actual versus Desired output/process of comparison and adjustment
